- Аннотация: We tested a relatively new effective CLIRAD(FC05)-SW radiation code [Tarasova, T.A., Fomin B.A., 2007] and the radiation block [Ritter, B.,Geleyn, J.-F., 1992]of the COSMO non-hydrostatic mesoscale model of the atmosphere and soil active layer [Doms G., Baldauf M., 2015; Doms G. et al., 2011] against the measured radiative data at the Moscow State University Meteorological Observatory (MO MSU). The radiation components were measured by the Kipp&Zonen net radiometer CNR4 with estimating all possible uncertainties of measurements by this instrument. The aerosol and the water vapor were measured by the CIMEL AERONET sun photometer measurements at the MSU MO [Chubarova N. et al., 2011]. The comparisons between the long-term MSU MO aerosol dataset and the other widely used aerosol climatology were made for different months. We showed the significant AOT overestimating in the older aerosol climatology. For example, the [Tegen et.al, 1997] AOT dataset is twice higher than real data for many months and 50% higher for annual means values. This bias provided a strong error in the calculation of the downward shortwave radiation. The uncertainty of the COSMO RT code was made against the new CLIRAD(FC05)-SW radiation model for different aerosol conditions. The application of various aerosol in COSMO RT codes has led to a pronounced temperature effects. We showed that in clear sky conditions the sensitivity of air temperature is about 0.5-0.8°C to the 100 W/m2 shortwave net radiation changes due to variations in typical aerosol over Moscow. The reported study was partly funded by RFBR (research project № 16-05-00985а).
